可调节线线连接器
本技术涉及单桩竖向静载试验中的反力牵拉装置,尤其是涉及一种可调节线线连接器。
技术介绍
土木建设施工中,为了桩基设计提供参考依据或者检验工程桩的成桩质量,会进行单桩竖向静载试验,单桩竖向静载试验必须有为之提供反力的加载反力装置。公告号为CN203569597U的中国技术公开了一种单桩竖向静载试验反力牵拉装置,该装置由连接于两预锚件之间的多根精轧螺纹钢筋和钢绞线组成牵拉结构,适用于大吨位和超大吨位的单桩竖向静载试验。相对于试验加载力,钢绞线拉断力较小,单桩竖向静载试验过程中,由于一根钢绞线受力不均引起的多根钢绞线甚至全部钢绞线的连续拉断,将导致试验的失败,故该反力牵拉装置中钢绞线的受力均匀程度成为关键因素。当钢绞线采用传统的不可调节线线连接器与预埋在锚桩桩顶的精轧螺纹钢筋连接,不能够调节钢绞线张紧度,造成钢绞线试验过程中的受力不均。公告号为CN106223370B的中国专利技术专利公开了一种可调节线杆连接器,该装置在调节连接套筒的两端通过相反的螺纹分别连接有调节头和锚固环套分别用于固定精轧螺纹 ...
